Question: Is it OK to use a ceiling fan in a bathroom?
This post was awarded #1 Answer at Yahoo! Answers
Some ceiling fans are specially made and UL listed to be used in damp or wet locations. Generally, these ceiling fans are marketed as “Outdoor” fans, but they are perfect for bathrooms as well as indoor pools or any other location where the fan will be exposed to moisture.
Damp rated fans are sufficient for your bathroom, but you can use a fan that is Wet rated as well. The only difference between the two is that wet rated fans can actually be installed outdoors in uncovered locations that are directly exposed to rain, whereas damp rated fans can handle moisture, but not be directly exposed to water.
